Secure Transmission of Patient Physiological Data in Wireless Body Area Networks Based on Enhanced and Modified RSA Cryptosystem and Run Length Encoding

The remote monitoring system's application in hospitals is getting more attention during the pandemic COVID-19 Lock down period. In this paper, patient physiological information like heart rate, body temperature, ECG, EEG, blood pressure, and glucose level, etc., are gathered by the body sensor networks, and will be transmitted to the doctors for remote treatment and emergency medical services. The confidentiality of the body sensed information is the main challenge while the transmission occurs in the public communication channel. This work helps to provide a security solution with the wireless body area networks, using Enhanced and Modified RSA algorithm (EMRSA) and Run Length Encoding (RLE). The compression algorithms are implemented to reduce the time of the encryption process. Our proposed scheme is a combination of Run Length Encoding Algorithm for data compression, and the Enhanced and modified RSA algorithm (EMRSA) for data encryption in wireless body area networks.
